Feb. 3, 1931. R. ULLRICH L 9L VALVE FOR CONTROLLING GASES AND LIQUIDS Filed Feb. 29, 1928 Patented Feb. 3, 1931' UNITED STATES REIMUN'D 'ULLRICH, OF'BERLIN, GERMANY VALVE FOR CONTBOLLIN GASES AND LIQUIDS Application filed February 29, 1928, Serial No. 258,052, and in Germany November 2, 1925.

The invention consists in a valve for gases and liquids which is particularly adapted for use with gas meters, and in which the outlet is closed by squeezing or compressing a flex- 5, ible member made in the form of a collapsible envelope or member of material such as thin leather or rubber.

The invention differs from known devices of this kind in that the flexible member is connected with a tilting operating valve plate which, in one inclined position, opens a passage in one direction and closes it in the other direction, while in the other inclined position the connection is closed in the first and opened in in the other direction.

It is preferable to connect several valve plates in pairs with the flexible member and to mount thein so that several passages can be controlled simultaneously but in different as directions.

This invention, which is particularly adapted as a controllingdevice for dry gas meters, possesses many advantages over the plane or tubular slide valves. and spherical or disc valves formerly used for this purpose due to its simple construction and easy manipulation, and since the surfaces to be sealed are, for the same opening, only half as long as in known closing devices, they can be main tained secure from leakage for a longer time.

The accompanying drawings show examples of constructions according to the invention.

Fig. 2.

In Figs. 1 to 4, and 6 a flexible member or tube 8 is shown composed of some flexlble or elastic material, such as rubber or leather. This member or tube is flatly compressed and its lower half It is fastened on a base plate or partition g, the upper half h of the envelope' being connected to and movable with the valve plate p which is preferably a channel plate provided with downwardly inclined edges Kc, 7c, the edges extending transversely over and externally of the whole breadth of the flatly compressed envelope 8. In the inner side of the envelope openings 1, are cut to correspond with openings 0, or, as shown in Fig.5, to openings (Z, d, d and d A rod I linked to the plate 1 can be pushed or pulled so as to rock or lift one side of thevalve plate p at a time, that is, the valve is opened and alternately tilted to either side, so that in one position of the plate p the passage 0 is opened to one side and closed to the other side, or vice versa, so that a passage is opened from the space above the base plate 9 through the passage 0 to the space below.

Each end of the envelope 8 is closed and secured to the partition 9 by a plate u extending transversely of t-heupper ply of the Z0 envelope; and a ring 9 clamped against the upper side of the lower ply of the envelope around the hole 25 in said ply secures said lower ply to the partition g. I The upper ply of the envelope is secured to the under side 7 of the plate 7) and a portion of said upper ply is folded around one end'of said plate and pinched between the upper side of said plate and a plate u.

' The valve system, when used as a controlling device for a dry gas meter, (Fig. 5), has a continuous flexible envelope 8 with valve plates 79, p, 30 p which are coupled in pairs by connecting rods '0 or o and are preferably under the action of springs f, f.

Measuring chambers 1', r T and r, are formed in the space below the partition 9 by a vertical partition and vertical flexible diaphragrns m and m one of said diaphragms being located on each side of said vertical partition. Openings t in the lower ply of the flexible tube or envelope 8 register with openings 01, (Z (Z and (5 formed in the partition 9 and leading, respectively, to said measuring chambers. Further openings t'in the 5 lower ply of the envelope 8 register respectiv y, with outlet passages a and min the partition g. The outlet passage a is immediately above the upper end of'the diaphragm m and is therefore common to the measuring chambers r and 1 and the outlet passage a is immediately above the upper end of the diaphragm m and is therefore common to the measuring chambers T and m.

The tilting valve plates 39, p are coupled by a connecting rod 2), and the tilting valve plates 2%, 71 are coupled by a connectmg rod '0 the connecting rods 0 and an being actuated, respectively, by springs f and f Links Z or Z of each valve pair are operated by two crank pins 2 and a which are relatively displaced at about 90, and the shafts w of the pins are driven in any known manner from the diaphragms m and m of the gas meter.

In the position shown by Fig. 5, the lefthand valves are closed, the right-hand valves being tilted to the right side and opened. As indicated by the arrows, the gas enters the measuring chamber m from the space above the partition 9 through the passage (Z presses the diaphragm m into the measuring chamber 1 so that the gas filling this chamher is driven out through the passages al and a connected by the attached part of the envelope 8; hen the diaphragm m is at the end of its stroke, it moves, through suitable mechanism, the shaft 10 about .a quarter of a turn in the direction indicated by the arrows, moving the pins 2 and a and thus actuating the rod 11 by means of the link Z to close the passages oh and (Z and also actuating the rod '0 by means of the link Z to tilt the left-hand valve plates 10 and p to the right, so that the measuring chamber 1" is connected with the inlet room above the base 9 through the passage d, while the chamber 1' communicates with the gas outlet through the passages (2 and a.

The gas entering fills the empty chamber 1 and, by moving the diaphragm m, presses out the gas from the replenished chamber 1 WVhen the diaphragm m has reached the end of its stroke, the shaft w is moved again, the valves {1- and 10 are closed, the valves p and 32 are tilted to the left to cause communication of the replenished chamber 1' through the passages d and a with the gas outlet, and also communication of the empty chamber'r through the passage d with the inlet room above the base 7. The diaphragm m moving to the left, again moves the shaft '20 to" cause the emptying of the chamber 1' through the passages 65 and a and the replenishing of the chamber 73 through the hole d The diaphragm m is pressed to the left, the shaft 10 is moved about a quarter of aturn, and thus all parts of the system have again reached the position illustrated in Fig. 5.

The rightand left-hand pairs of valves close and open alternately to either side, causing the filling and emptying of one measuring chamber after another and oscillating the shaft w. I

In dry gas meters with only one diaphragm,

the present valve system may be employed as a controlling device.

I claim: I v 1. The combination with a partition having a port therethrough, of a valve mechanism therefor including an elongated open ended flexible member having an upper and lower layer resting upon the partition and having an opening formed through the lower layer thereof registering with said port, a plate attached to the upper layer of the member above the port and opening, and means for rocking said plate to cause the port to be covered or be opened from either side.
